Preventing Intimate Partner Murder–Suicide: A Case-Control Study of Suicidal Males in Abusive Relationships
Introduction
Murder–suicide is a rare but serious public health problem. It often occurs in the context of intimate partner violence; 62% of murder–suicides in the U.S. involve killing an intimate partner. The goal of this study was to identify the risk indicators for intimate partner murder–suicide among suicidal males with a history of perpetrating intimate partner violence.
Methods
This case-control study used National Violent Death Reporting System data, 2019–2020. Cases were intimate partner murder–suicides committed by males. Controls were males who perpetrated intimate partner violence but who died by suicide without killing their partner. The research team reviewed text summaries from the National Violent Death Reporting System to code detailed information about each event. Analyses estimated the adjusted odds of intimate partner murder–suicide using generalized estimating equations and were completed in November 2024.
Results
Among 478 matched case/control pairs, firearm use (AOR=5.3) and decedent military history (AOR=1.8) were associated with increased odds of perpetrating intimate partner murder–suicide. Prior involvement in a domestic violence protection order (AOR=0.4) and previously established suicide risk indicators (e.g., appearing depressed [AOR=0.4], prior suicide attempts [AOR=0.2], disclosed suicidal intent [AOR=0.2]) were associated with decreased odds of intimate partner murder–suicide.
Conclusions
Among suicidal males perpetrating intimate partner violence, several factors differentiated the risk for murder–suicide relative to that of suicide only. Improving accessibility and implementation of domestic violence protection orders while removing firearms from people who are perpetrating intimate partner violence may prevent intimate partner murder–suicide. There may also be opportunities to screen for and jointly address suicidality and intimate partner violence perpetration across military, healthcare, legal, and child welfare settings.
期刊介绍:
The American Journal of Preventive Medicine is the official journal of the American College of Preventive Medicine and the Association for Prevention Teaching and Research. It publishes articles in the areas of prevention research, teaching, practice and policy. Original research is published on interventions aimed at the prevention of chronic and acute disease and the promotion of individual and community health.
Of particular emphasis are papers that address the primary and secondary prevention of important clinical, behavioral and public health issues such as injury and violence, infectious disease, women''s health, smoking, sedentary behaviors and physical activity, nutrition, diabetes, obesity, and substance use disorders. Papers also address educational initiatives aimed at improving the ability of health professionals to provide effective clinical prevention and public health services. Papers on health services research pertinent to prevention and public health are also published. The journal also publishes official policy statements from the two co-sponsoring organizations, review articles, media reviews, and editorials. Finally, the journal periodically publishes supplements and special theme issues devoted to areas of current interest to the prevention community.
